First issue solved!!
To access the request object in the jsp using struts2 tags this is what we
have to do
<s:property value="#parameters['requestattributename']" />
if ur url was *.action?abc=xyz then
<s:property value="#parameters['abc']" /> would give the value of the
request parameter called abc and print xyz in this case. So learning is tat
we have to use #parameters[''] instead of #request[''] which was what I was
trying to do earlier!
